You could use XYRemap, but I also already wrote Widen for this exact purpose, which works in all 8-bit colour spaces (but is 64-bit only).

If you're looking for a formula, it involves tan or inverse tan, can't remember which way round I did it.

You could also try messing around with Defish which may mitigate the ugliness of edge distortion on pans by introducing some vertical distortion as well.

I will prefer the specialist plugin, its precision is probably higher than an 8-bit LUT. And even better it's available for x86-64.

Not sure what LUT you are referring to.

If I use an RGB24 image as distortion map (a.k.a. look-up table), the resolution of the distortion would be 8 bit at most. I guess it might be coarse enough to see some "motion banding" in panning scenes?!

That was a suggestion by someone that never got implemented. xyremap works purely on calculations of target coordinates to source coordinates. Widen doesn't use a LUT either.

Apparently I mixed that up with an earlier idea what I was looking for... one day I notice the UPN in the description, the other day I completely forget about it.
